In the first example, we discuss the Fitz-Hugh Nagumo (FHN) model that explains neural dynamics in a simplistic way [1]}. This has been used as a test case to discover the model using dictionary-based sparse regression [2]}. The dynamics are given as follows:
\(\begin{aligned}(t) &= (t) - (t) - \tfrac{1}{3}(t)^3 + 0.5,\\(t) &= 0.040(t) - 0.028(t) + 0.032,\end{aligned}\)
